如何获得ios系统版本号、设备名称

获得IOS系统版本号

1 [[[UIDevice currentDevice] systemVersion] floatValue]

获得硬件名称

 1 + (NSString*)getMachine{
 2     size_t size;
 3     sysctlbyname("hw.machine", NULL, &size, NULL, 0);
 4     char *name = malloc(size);
 5     sysctlbyname("hw.machine", name, &size, NULL, 0);
 6     
 7     NSString *machine = [NSString stringWithCString:name encoding:NSUTF8StringEncoding];
 8     
 9     free(name);
10 
11     if( [machine isEqualToString:@"i386"] || [machine isEqualToString:@"x86_64"] ) machine = @"ios_Simulator";
12     else if( [machine isEqualToString:@"iPhone1,1"] ) machine = @"iPhone_1G";
13     else if( [machine isEqualToString:@"iPhone1,2"] ) machine = @"iPhone_3G";
14     else if( [machine isEqualToString:@"iPhone2,1"] ) machine = @"iPhone_3GS";
15     else if( [machine isEqualToString:@"iPhone3,1"] ) machine = @"iPhone_4";
16     else if( [machine isEqualToString:@"iPod1,1"] ) machine = @"iPod_Touch_1G";

18     else if( [machine isEqualToString:@"iPod3,1"] ) machine = @"iPod_Touch_3G";
19     else if( [machine isEqualToString:@"iPod4,1"] ) machine = @"iPod_Touch_4G";
20     else if( [machine isEqualToString:@"iPad1,1"] ) machine = @"iPad_1";
21     else if( [machine isEqualToString:@"iPad2,1"] ) machine = @"iPad_2";
